Larry,

Your reply got me thinking. I called it a taper gauge, when I should have said dial bore gauge. Your comment about the taper gauge not looking too sophisticated threw me. A taper gauge does look low tech...a dial bore gauge looks a little better.

I don't know if it would be worth it to buy one of these for a one time engine job..maybe a friend has one, or just use your inside micrometer. The link shows what I meant the first time! smile
